Specification of Letters Patent.

Patented Sept. 19, 1911.

Application filed January 30, 1911. Serial No. 605,512.

To all whom 'it may concern."

. Be it known that I, Louis B. HAZEN, a citizen of the United States,residing at Hudson, in the county of Lenawec and State of Michigan, haveinvented a new and useful Waste-Paper Press, of which the following is aspecification.

The device forming the subject matter of this application, is a bailingpress, adapted to compress into bundles, waste paper, excelsior, leatherand other similar materials which are commonly baled for shipment.

It is the object of this invention to provide a baling press having atrunk of novel and improved form, whereby great rigidity is obtained; toprovide novel means for advancing and retracting the follower; and toprovide novel means whereby a retaining hoop may be applied to thecompressed bale.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of invention herein disclosed can be made within the scope ofWhat is claimed without departing from the spirit of the invention.

In the accompanying drawings,--Figure 1 is a front elevation, partsbeing broken away; Fig. 2 is a side elevation, parts being broken away;Fig. 3 is a transverse section in a plane taken adjacent the top of thetrunk; Fig. 1 is an elevation of the pawl and ratchet mechanism; andFig. 5 is an edge elevation of the operating mechanism, adjacent partsof the structure being shown in section.

The trunk in which material to be compressed is inclosed, may consist ofsills 1, across which extend bars 2. Supported by the bars 2, is aplatform 3. Resting about the platform 3 and rising above the. same, areside walls at, the back of the trunk being denoted by the numeral 5. Inthe back 5 of the trunk there are longitudinally extended openings 6,alined with openings 6 in the platform 3, the back 5 and the platform 3being, if desired, formed of a series of spaced strips.

The side walls 4: and the back 5 are surrounded by a top frame 7,carrying a closure 8. Resting upon the cross bars 2, and ordinarilysecured thereto and to the side walls 4:, are lower cleats 9, upon whichrests a rear cleat 10, which may be secured to the back 5. Secured tothe side walls 4, and located between the top and the bottom of thetrunk, are intermediate cleats 11. Extended across the back 5, andpreferably secured to the back, are rear cleats 12, the cleats 12 beingdisposed above and below the intermediate cleats 11, in contacttherewith. Strap bolts 14 are extended downwardly through the cleats 11and 12, through the cleats 10, into engagement with the lower cleats 9,to bind these elements together, the strap bolts 15 being terminallymounted in the top frame 7 and in the lower cleats 9, these bolts beingprolonged through the intermediate cleats 11, as seen most clearly inFig. 2.

The trunk thus formed, is open at its front, and to close the front ofthe trunk, a lower door 16 and an upper door 17 are provided. Extendedacross the lower door 16, and secured thereto, are cleats 18, rotatablymounted upon a bolt 19, terminally mounted in the cleats 11 and 9.Suitable latches 20 are mounted upon the cleats 18, and engage one ofthe side walls of the trunk, to hold the door 16 in closed position. Theupper door 17 is cleated as shown at 21, and is united by means ofhinges 22 with the same side wall at of the trunk with which the latches2O engage. The construction, therefore, is such, that the doors 16 and17 swing open in opposite directions. The upper door 17 may be suppliedwith a latch member 23, of any desired construction, engaging one sidewall of the trunk, to hold the door closed.

Mounted for vertical reciprocation in the trunk thus formed, is afollower 24, to the upper face of which bearings 25 are secured, a shaft26 being jom-naled for rotation in the bearings, the extremities of theshaft 26 protruding outwardly through longitudinal slots 27 in the sidewalls 1 of the trunk.

The adjacent edges of the top frame 7 and one of the intermediate cleats11 are recessed, as shown at 28, to receive the ex tremities of a rack29, held in place by a securing plate 30, overlapped upon the frame 7and the cleat 11.

Secured to the shaft 26, is a pinion 31, meshing into the rack 29.Likewise secured to the shaft 26, and located beyond the pinion 31, is aratchet 32, adapted to be engaged by a pawl 33, pivoted intermediate itsends upon a bracket 34, the bracket 34 being extended inwardly throughone of the slots 27, into rigid union with the follower 24. One end ofthe pawl 32 is counter-weighted, as shown at 35 in Fig. 5, so that thepawl 33 will be held gravitationally in engagement with the ratchet 32.

Mounted for "rotation upon one of the protruding ends of the shaft 26,is a lever 36, provided with outstanding ears 37, in which is slidablymounted a pawl 38, a spring 39, bearing at one end against one of theears 37, and at the other end against the pawl 38, serving to advancethe pawl into engagement with a ratchet 40, secured to the shaft 26beyond the ratchet 32. A releasing lever 4C1 is pivoted intermediate itsends upon the lever 36, one end of the lever 4-1 being united with thepawl 38 by a suitable connection 42. Secured to the tremity of the shaft26, beyond the lever 36, is a crank 43.

The operation of the device as above described is as follows:Presupposing that the follower 24 is in the uplifted position shown inFig. 1, the upper door 17 is swung open, whereupon the waste paper orother material which is to be baled, is disposed within the trunk, thelower door 16, preferably, being closed. When the proper amount ofmaterial has accumulated within the trunk, the upper door 1.7 is swungto closed position and locked. The lever 36 is then oscillated, the pawl38 engaging the ratchet 40, and causing a rotation of the shaft 26, thepinion 31 meshing into the rack 29, and forcing the follower 2%downwardly, thus compressing the material which is in the trunk. Thecompression of the material thus secured, will be maintained by theengagement between the ratchet 32 and the pawl 33. hen the desiredcompression has been secured, in order to elevate the follower 24, thecrank 43 may be manually operated, causing a retraction of the follower24, the pinion 31 traversing the rack 39 and elevating the follower 24into the position shown in Fig. 1. When it is desired to hoop thecompressed bale, one or more bands of wire or the like may be extendedthrough the openings 6 and 6 in the back 5 and in the platform 3respectively, the lower door 16 having been swung open; whereupon, thefree ends of the securing hoops or bands may be united at the front ofthe bale.

Having thus described the invention, what is claimed is 1. In a deviceof the class described, a trunk; a follower mounted for reciprocation inthe trunk; a shaft journaled for rotation upon the follower and locatedin the trunk; a rack secured throughout its length to the trunk; apinion secured to the shaft and adapted to mesh into the rack; a ratchetsecured to the shaft; a pawl pivotally mounted upon the follower andadapted to engage the ratchet; a lever rotatable upon the shaft; asecond ratchet secured to the shaft; and a spring pressed pawl upon thelever, adapted to engage the last named ratchet.

2. In a device of the class described, a trunk; transverse elementssecured to the sides of the trunk, and provided in their adjacent edgeswith oppositely disposed recesses; a rack terminally engaged in therecesses; a securing element extended longitudinally of the rack andoverlapped upon the transverse elements; a follower mounted forlongitudinal reciprocation in the trunk; a shaft journaled for rotationupon the follower and located in the trunk; and a pinion upon the shaft,meshing into the rack.

In testimony that I claim the foregoing as my own, I have heretoilffiXGCl my signature in the presence of two witnesses.
